Check Digit Verification of cas no

The CAS Registry Mumber 22703-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,7,0 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22703-65:
(7*2)+(6*2)+(5*7)+(4*0)+(3*3)+(2*6)+(1*5)=87
87 % 10 = 7
So 22703-65-7 is a valid CAS Registry Number.
